"Magnetorotational supernova"
S.G. Moiseenko (IKI)
Abstract:
We
present 2D results of simulations of the magnetorotational core collapsed
supernova. For the first time we obtain strong explosion for the core
collapsed supernova. In 2D approximation we show that amplification of the
toroidal magnetic field due to the differential rotation leads to the
formation of MHD shockwave, which produces supernova explosion. The
amounts of the ejected mass and energy can explain the energy output for
supernova type II or type Ib/c explosions. The shape of the explosion is
qualitatively depends on the initial configuration of the magnetic field,
and may form strong ejection neat the equatorial plane, or produce mildly
collimated jets. We discuss the violation of the mirror symmetry of the
supernova explosion in magnetorotational mechanism and possible
explanation for the origin of the observed rapidly moving neutron stars.
